Need Help Identifying Unmarked RCA Interconnects..

As the title says - I need some help identifying these unmarked RCA cables. They were purchased by my father but he doesn't remember anything about them. I have compared them to a few different cables at the $100 and below mark and these unmarked cables are definitely in a much higher league, much more refined (DIY RCAs, BJC LC-1, Audioquest Silver Extreme). Today I should have the time to compare these RCAs to a set of Kimber Heros so we will see how they stack up to a higher level RCA. Anyways, any help would be greatly appreciated. I posted pictures of the cord on my Flickr account. Please see the link..
